Questions on the "Subie Newbie Tuning Guide"
I read BadNoodle's "Subie Newbie Tuning Guide" and have a few questions that will also help other "tuners"
Quote:
Quote:
- If I already have a Stage 2 map, how much timing should I remove for it to be safe? 4*? - I'm guessing by him saying "make sure you are running rich", it pertains to my first questions above. Quote:
So I found my 75%, obviously I should not target that throughout the every cell in the Target Boost table. I know at low RPM's and low G/S that obviously it shouldn't target rich. Unless I'm wrong about that also. What is a rule of thumb on how to make this table from scratch? I'm trying to learn the "rules of thumb" for tuning from scratch. I already have a stage 2 map I am working on, but want to learn more in-depth and possibly make my own MAP from scratch.

I think you need to spend a LOT more time reading the basics of engine tuning before worrying about the details of making your own map. Once you understand what exactly the maps are doing, it becomes much clearer where you make changes. It is good that you are asking questions here and being safe, not wanting to make changes blindly. But there is a lot more to read first besides the Guide before you should consider yourself set to make some changes.

That is just a guide and not 100% "the rules". As far as the OL fueling I'm sure he means redline. Unless you have done a turbo swap there is no reason to remove timing,richen the fueling or reduce the boost on a stage 2 tune just to re-tweak it. You have not even stated what your doing or your goal. I agree with what was said above. If your this confused you really need to read more. Most people tuning their own WRX's have been turning wrenches and tuning other types of engines/cars (fuel injected or carburetor) for years/decades.

Explain what? You want some one to sit down and just explain to you how to tune every part of the ROM? Are you more special than everyone else? Welcome to Opensource Tuning.....you want all the answers? Take an EFI 101 class............

Wow I feel the love. No you don't have to explain it all to me, I'm just asking what I don't understand. |

I recently took EFI101 and enjoyed it. More of Theory and less about tuning.
Jeff Hartmans book is awesome . |

I have seen your posts both on here and Romraider. You act like nobody is answering your questions when they are. People keep telling you to read because they can clearly see you need to learn to crawl before you can walk. All the information is 100% on Romraider and in the Engine Management forum here. It's funny how everybody expects everyone else to always step up do the work for them. People help them and then when they don't they get butt hurt. The search function is fixed and working very well now on this site. Now you can get pissy for me telling you that but what you don't understand (and most other people) is by searching you learn probably 300% faster due to all the information you encounter trying to find the actual information you want. People in this day and age want everything right now. I mean RIGHT now. You kind of need to have the ability to actually find and locate information on your own to some degree. You also just have to sit down and play with the software and figure stuff out on your own,the same as everybody else did. Not everybody uses Badnoodle's Guide. In fact when he wrote it he himself was just learning to tune. I would say 50%-75% don't use it. He did a good job on it but it is strictly for beginners to to get a general idea/theory of one way to go about tuning.

I think the EFI102 has more "hands on" as far as tuning. Greg Banish's book is quite good too. Jeff Hartman's Turbocharging Performance Handbook is written quite nicely as well.

I have an APS 525 FMIC. I'm not actually trying to run 20psi. It was just an example. Quote:
Quazimoto, I understand where you're coming from. I have searched and some of the questions I seek aren't fully answered. I will do my best in searching. I have Jeff Hartman's book and currently reading it. I will probably get the Engine Management: Advanced Tuning by Greg Banish as well. |

Thorne, do you recommend taking the EFI 101 first? Or 102?

Seriously? Holy crap..............what part of "learning to crawl before you walk" did you not understand? Go to EFI101.COM AND READ THE CLASS MATRIX. Considering you think rescaling your MAF will help get rid of your boost oscillations then yes you would take EFI101 before EFI102 as 102 is the "advanced" course. You are far from "advanced"...........

I will look into it. Didn't particularly read the class outlines.

Thanks fbu. Your help on RR is great.
It's alright. Don't really care other than the drive of wanting to learn to tune. I've been just trying to gather the information that's not completely outlined in threads that have talked about my questions. |

Thanks for the help. My LC-1 should be arriving tomorrow (amazon ftw), so I'll be able to dial everything in now

Wow, just found this thread so I thought I'd answer:
When writing the guide, I planned for the worst. You don't have to follow anything, a lot of it is a bit over the top in terms of safety. Yes, you don't have to run that rich, remove timing, or all boost IF you've done everything correctly mechanically. But if you did something stupid liked hooked up the boost controller ncorrectly, then taking all those safety precautions will help to save your engine while you go for a spin and realize that's something is wrong. Hope that clears it up |

http://en.wikipedia.org/wiki/Linear_interpolation You cant do interpolation in romraider......but ecuflash has it. Open up base timing in ecuflash. go view -> graph hilight a column or row. then go file -> interopolate horizontally (row) or interpolate vertically (column) You will see what happens. Quote:
i target 10.5-10.8 on cali 91 oct......we need the fuel to be able to run the timing necessary to keep the EGT's down. he can do whatever he wants on 93 octane and e85.....but "starting" at 11:1 on 91 oct isnt really a good idea. |

Ecuflash Is solely what I use to
Modify roms. It runs way faster with the individual def files and it graphs and does interpolation nicely too. The only thing I use romraider for is copy/pasting the tables into airboy. |

wade....with all due respect.....you are on here asking for maps....and pm'ing people for maps and at the same time posting in peoples threads trying to give out advice.
just take a step back and read for about 6 months, do some testing on your own car and form a solid foundation of knowledge before you try to give advice to others. and you pm'd me about a map. my view on this is kind of weird. I browse the OS forums and try and help people. if i help them and they know im a vendor on here (phatbotti tuning) they usually thank me and send a little money to me for the help. so i will tune peoples cars for free that have posted looking for help....but i really dont like just sending people maps for free that pm me. its kinda weird....but it makes sense to me. |
